Abstract (en)
[origin: WO2020191553A1] System and methods for mounting of material samples via a vacuum system (100) and controlling fluid flow through a tube of the vacuum system (100) are disclosed. In some examples, the vacuum system (100) may be a castable and/or cold mounting vacuum system (100) that facilitates mounting and/or encapsulation of material samples in epoxy resin under low, vacuum, and/or near vacuum pressure. In some examples, the vacuum system (100) may comprise a flow control device (500) configured to control epoxy flow through a dispensing tube that connects to a hollow vacuum chamber (104). In some examples, the vacuum chamber (104) may have an opening (134) defined by a rim (130) sandwiched between upper and lower portions of a sealing ring (132). A movable lid (136) may be configured to press down on the upper portion of the sealing ring (132) when in a closed position, so as to seal the opening (134).
